In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix DMA address corruption due to findvma misuse fastrpcgetargs uses findvma to look up the VMA for a user-provided pointer and compute a DMA address offset. When the address falls in a gap before the returned VMA,...

CVE-2026-53159

The CVE-2026-53159 entry describes a Linux kernel vulnerability in the fastrpc path where fastrpc_get_args() uses find_vma() to locate the VMA for a user pointer and compute a DMA address offset. If the address lies in a gap before the returned VMA, (ptr & PAGE_MASK) - vma->vm_start underflows...
